|
| |
| ROXY-1 Specifications: |
| Input Sensor: For oxygen, either (a) Sable Systems fuel cell, not harmed by moisture, CO2 or particulates; 18-36 month life in normoxic service, user-replaceable, or (b) any user-supplied oxygen analyzer or oxygen sensor. For other variables, such as CO2, water vapor etc., any user-supplied analyzer or sensor with a voltage output (usable range from 0 V to a full scale of 2 mV - 5.5 V) |
Input Gain Setting: 1 - 1,000, fully automatic
|
Accuracy and Resolution: Voltage measurement accuracy 0.1%, resolution better than 1 part in 50,000, depending on magnitude of input signal
|
Gas Switcher: High speed electrical valve. Maximum applied pressure 25 p.s.i. (170 kPa)
|
Control Type: PID (Proportional Integral Derivative). All PID settings can be changed by the user
|
| Analog Output: Multi-range, 12 bit resolution, 0-4V output |
Serial I/O: RS-232 serial, 115200 baud. Unit can output a text string containing setpoint, reading, and gas pressure at user-settable interval (0.2 sec - 1,000 sec), or it can operate in polled mode for remote control (open protocol; program supplied)
|
| Pressure sensor: Range 0-200 kPa, accuracy 1% (can be user-calibrated to greater accuracy if desired). Resolution 0.1 kPa |
| Internal A/D Conversion: 24 bits |
| User Interface: Intuitive menu system backed by nonvolatile memory of user settings. Single-click spanning at default span settings |
| Panel Display: Digital 2-line alphanumeric LCD, simultaneous display of setpoint, reading, control drive and inlet gas pressure |
| Tubing Fittings: Nickel plated barb fittings for 1/8" (3 mm) i.d. flexible or semi-rigid tubing; other fittings available to special order |
| Power Requirements: 11 - 14VDC (12 VDC nominal), < 100 mA. 110VAC or 220VAC adapter supplied |
| Operating Temperature: 0 - 50 degrees C, relative humidity non-condensing |
| Size/Weight: 6" x 6.5" x 2.5" (15 x 16 x 6 cm); less than 3 lbs (1.5 kg). |
